Have Yourself a Merry Little Christmas might just be my favorite Christmas song (along with Baby, It's Cold Outside, which, incidentally, Zooey covers as well. Oh, and I love O Holy Night. And All I Want for Christmas is You. And Jesu, Joy of Man's Desiring...)
Below, Zooey sings Have Yourself... for Conan O'Brien. She's lovely. And she has a nice voice, too. Sigh.
